JOSEPH DE ROSE, OF PHILADELPHIA, PENNSYLVANIA WATER-CLOSET Application filed November s, 1928. Serial 110,317,075.

This invention relates to water closets and more particularly to the type having a flushlwater tank forming part of the bowl and valve mechanism which, when the closet seat is relieved of pressure, ensures thorough 1 V flushing of all parts of the bowl. I

The primary object of my present improvements is to provide an anti-freeze water closet, of the above noted type; or, in other words, I aim to furnish a water closet adapted for outside installation, without liability of its becoming inoperative in cold and frosty Weather. r I 1 Another object is the provision ofa simple and efficientdistant service-supply control and a local flush control with means co-ordinating the same for alternate opening and closing. i A

A further object is to'provide an'automatic water closet which is thoroughly sanitary and does not involve provisionof a pit when installed out of doorsf 1 Other objects embrace the novel details of construction, combinations and arrangements of parts, hereinafter fully described, shown by the accompanyingsheet of drawings, and specifically defined in the'appended claims.

To the foregoing ends invention essentially consists in locating the service-supply control below normal freezing level and adirect-connected local flush control,'with novel operating means 'co-ordinat-ing actuation thereof by pressure applied to'and relief of pressure from-the closet seati- In the drawings r i Fig. I is a verticalsect'ional view of a water closet embodying my present improvements.

Fig. II is arelatively enlarged sectional view showing the "service-supply and flush controlling mechanism, part being broken out for convenience in iliustration; and,

Fig. III is a further enlarged sectional detail taken approximately on'the plane designated IIIIII in Fig. II.

Referring morein detail to the drawings, the numeral 5 generally designates-a water closet bowl of conventional type, and more particularly adaptedfor outside useythat is tosay it is devoid of a water seal concavity inits lower portion. This bowl 5 is provided with a discharge outlet 6 for appropriate connection at 7 tothe soil or sewer pipe 8, as well as a basal flange 9 whereby it is secured to the floor 10 by fastening means 11, with interposition of a suitable sealing gasket'12." Formed integral with the bowl 5 about its top is an annular flush water reservoir 13, having communication-through a valve controlled port 14 in a separating diagram l5- into the subj acent distributing ring or channel 16 which discharges into said bowl by way of perforations 17 in the usual way.

For the purpose of controlling the filling of, and flushing from, the reservoir 13, I make use of the novel valve and actuating mechanism therefor, now to be described. Fitted to the upper end of the service pipe 18, by means of an appropriate union coupler 19, is a valve casing 20 of tubular formation that is providedinteriorly with radial ribs 21 which determine flow passages 22, while affording guidance for a plunger type valve 28 adapted to co-operate with a concentric seat 24 in'said casing, in controlling supply and cut-off by way of the service pipe 18. It is to be particularly observed that the valve casing 20 is located well below the ground or floor level 10; or, in such a position as is well below normal ground freezing level in the vicinity of the closet installation. Furthermore, it is noteworthy that I provide the valve casing 20 with a lateral outlet 25 communicating by a downwardly inclined tubular connection 26 and coupler nipple 27 into the soil or sewer pipe 8, for a purpose later on explained.

Conveniently screw-threaded and sealed into the upper endof the valvecasing 20 is a vertically directed pipe 28 which passes through the floor 1 0, and'is furnished at its upper end with a union coupler 29 whereby relative to the diaphragm'15 and distributor channel 16, in a lateral ofiset 16 of the latter, by means of upper and lower sealing gaskets 35, 36 respectively, and a lock nut or nuts 37 in an obvious manner.

Sl'idably fitting the upper portion of the plunger casing 30 is a tubular cap 38 having an invert dished flange 39 for co-operation with the annulus 34, as hereafter set forth, and a co-axial integralor attached stem 4E0 reciprocable axially through a stuifing'box 41, forming part of a cupped attachment 42 sealed in an aperture 13 of thetop wall of the flush water reservoir 13, through the me dium of a compressible gasket 43 and conventional attaching means 44 The tubular cap 38 is normally maintained in the elevated position shown under the influence of a compression spring 45 housedtherein between the closed-in upper end 46 thereof and the top edge of the plunger casing '30; and,

.saidcap'is provided with a series of elongated orifices 47 about its tubular wall for a purpose hereafter explained. In addition to the function just mentioned of the. spring 45, it also serves to support the'weight of the closet seat 48 and to normallylhold the same slightly elevated relativel'to the closet bowl 5, asillustrated; said seat being hinged at 49'to a conventional device 50, sealed in an-offset 51 of the aforesaid flush-waterreservoir 13. I Provided within the upper portion of the plunger casing 30 are a series of radial ribs 52, similar in character and purpose to the ribs 21 hereinbefore described, that serve to afford guidance for a piston member 53 formed onor attachedgto-the upper end of an actuator or connecting ro'd54, securely connected to the plunger valve 23 which controls the service connection 18. Operative connection between the piston member 53 and the tubular cap 38 is afiordedby motion translating devices 55, connected at 56 with freedom for limited longitudinal'movementbetween spaced cars '57 on the dished flange 39, and which pass through appro- 'priate slots and orifices 5'8, 59, respectively in the body portion of said cap 38 and the upper end of the plunger casing '30. It is also to be noted that the free ends of the motion translating devices'55-operatively engage in Y a comparatively deep groove 60 in the piston member 53; while they are enlarged'or fashioned substantially spherical at 61 where theyengage in the orifices 59, whereby they are aiforded fulcrum bearing thereat,

The operation of my improved antifreeze closet is briefly as follows As the hinged seat 48 is depressed by a user of the closet, the resistance of the compression spring 45 is overcome, withtlie result that the eta-n40 and tubular cap 38 are moved downward until the dished flange 39 engages andjseats on the annulus-34, thereby closing communication between the flushw'ater reservoir 13 and the distributor ring 7 or channel 16. Concurrently with the movement just described the motiontranslating devices 55 are rocked upon their fulcrum voiding out through the elongated cap orifices 47 past the piston member 53. lVith closure of the port 14: and apertures 32 by the dished cap flange 39, a certain amount of airwill be trapped in the reservoir 13 and compressed .by the inrushing water from service 18, the flow of said water continuing until an equalization of pressure obtains;

hen the seat 48 is released incident to the user, rising therefrom, .the compression spring4'5 instantly functions to elevate the tubular cap .38 with concurrent raising of the seatx'by the stem 40 to normal inactive location, whereby the piston member 53 is simultaneously loweredby the devices 55and the plunger valve 23, seated, thus shutting-off further flow from "the service connection 18. Incident to the movements *just set forth, the water stored in the reservoir 13 is expelled .via the apertures 32. and port 14, into the distributor channel '16 for forced dissipation through the perforations 17 about the wall of the closet bowl 5, there- I by effectively flushing the same, such operation being expedited under pressure of the H air trapped as described above in connection with the reservoir filling period. Furthermore, as a result of the action just set forth,

closet that is entirely automatic and particularly adapted for out ofdoors use-whileiiot so restricted, the same being simple inconstruction and devoid of any parts liable to become deranged or get out of order under constant use or careless m suse. I
